$PECIFIGATION forming part of Letters Patent No. 741,414, dated October 13, 1903.

Application filed June 26, 19 03.

T0 aZZ whom it may concern:

Be it known that I, EDWARD H.RYAN,a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented new and useful Ini-' provement-s in Vehicle Jacks, of which the following is a specification.

My invention consists of an improvement in the vehicle-jack for which Letters Patent of the United States No. 349,179 were granted to me on the 14th day of September, 1886, the present improvement consisting in adapting the journal of the lifting-bar and elbowlever to form guides for said bar in its ascent and descent, thus providing for increased strength of said bar and a reduction of expense in the construction of the jack.

Figure 1 represents a side elevation of a vehicle-jack embodying my invention. Fig. 2 represents a vertical section thereof in operative position. Fig. 3 represents a horizontal section thereof.

Similar letters of reference indicate corresponding'parts in the figures.

Referring to the drawings, A designates the base of the jack, B the standards, and G the lifting-bar thereof. In the standards are the vertical slots D, and in the lifting-bar is the slot E, said slots D receiving the gudgeons F,

which project from the sides of the liftingbar, and said slot E receiving the rod or bar G, which is secured to the standards. To the lower end of the lifting-bar are pivoted by an axial bolt H the elbow-levers J, which are mounted on the roller K and provided with the handle L,said roller running on thebase A.

The gudgeons F are continuities of the axial bolt H and integral therewith, it being seen that in the ascent and descent of the liftingbar said gudgeons guide the same true and uniformly, it being also seen that as the handle is lowered the roller advances and the elbow-lever raises the lifting-bar, this being accomplished in an easy and powerful manner.

In my previous patent the lifting-bar re quires to be pierced at a plurality of places, one for the guiding-pin and the other for the connecting-pin of the elbow-levers, said bar Serial No. 163,226. (No model.)

thus having a plurality of pins thereon. In the present case, as the gudgeons F are continuous of the axial bolt II, I avoid one of the piercings in the lifting-bar of the previous patent, thus correspondingly preserving the strength of said bar, while also reducing the expense of the article. The roller acts as a movable fulcrum, so that whenit is advanced the lever turns thereon, causing the forward limb of said elbow to turn from a horizontal to a vertical position, and so elevate the lifting-bar. When the roller is run back, the lever, assuming its normal position, permits said bar to descend.

Various changes may be made in the details of construction shown without departing from the general spirit of my invention, and I do not, therefore, desire to be limited in each case to the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a vehicle-jack of the character stated, a standard, the same having a vertical slot therein, a lifting-bar, an elevating-lever, an axial bolt connecting said lever and bar and a gudgeon freely entering said slot and comprising a lateral continuity of said bolt.

2. A vehicle-jack having a standard, a lifting-bar, an elevating-lever connected by an axialbolt with said bar, said bar and standard having vertical slots therein and a gudgeon entering the slot of the said standard and being laterally continuous of said axial bolt.

3. In a vehicle-jack, a lifting-bar, a standard, said bar and standard having vertical slots therein, a pin on said standard freely entering the slot of said bar, an elevating-lever, an axial bolt connecting said lever with said lifting-bar and a laterally-projecting gudgeon continuous of said bolt and freely entering the slot of said standard.
